Low-Profile Rotary Axis

Low-Profile Rotary Axis


Hardinge Inc. (www.hardinge.com) said its new GD210LP lowprofile rotary table provides rigidity, speed, accuracy and repeatability in an affordable package.

High stiffness and rigidity are accomplished with large-diameter bearings and a fail-safe clamp system allowing part weights to 220 lb. Radial load testing resulted in a stiffness four-times greater than a competitive model.

The GD210LP produces as much as 233 lb-ft (315Nm) of clamping torque to handle off-center drilling, cross-axis milling and other highforce cutting applications.

A fast clamp and release in milliseconds reduces cycle time.

The unit’s hardened and ground steel cross-axis helical gear provides long life and continued accuracy.

The unit has a precision ground, 210-mm slotted face plate and features rapid table rotation to 40 rpm. The face plate can be removed to mount a manual jaw chuck directly to the A2-5 spindle to allow for the gripping of round parts. The rotary table can be operated as a stand-alone unit, in horizontal or vertical positions with a servo control, or as a true fourth axis connected directly to the machine.

The low-profile footprint requires minimal space on the table to allow vises or other fixtures to remain in place for other jobs and to reduce setup and teardown time.

Accuracy is ±15 arc-sec with ±3 arc-sec repeatability Double eccentrics design provides for high-quality gear mesh. Customers can perform future gear wear compensation for extended life and improved accuracy over time.

Units will be available for delivery in December 2008.
